Interlinking

Linked Data is a method to publish data on the Web and to interlink data between different data sources. Linked Data can be accessed using Semantic Web browsers, just as traditional Web documents are accessed using HTML browsers. However, instead of following document links between HTML pages, Semantic Web browsers enable surfers to navigate between different data sources by following RDF links. RDF links can also be followed by robots or Semantic Web search engines in order to crawl the Semantic Web. See Linked Data – The Story so far and How to publish Linked Data on the Web for more information about Linked Data.

The DBpedia data set is interlinked with various other data sources (see voiD description). The diagram below (Linking Open Data cloud diagram, by Richard Cyganiak and Anja Jentzsch. http://lod-cloud.net/ ) gives an overview of some of these data sources:

1 The W3C Linking Open Data Community Project

DBpedia is part of the W3C Linking Open Data community project, an effort to publish and interlink various open data sources. As of September 2011, this effort has built a Web of interlinked data sources that amounts to more than 31 billion RDF triples. Please refer to the project's data sets page for a list of all published data sets.

2 Linking to DBpedia from Your Dataset

The Silk Link Discovery Framework can be used to generate new links to DBpedia based on user-provided link specications which are expressed using the Silk Link Specification Language (Silk-LSL).

3 Linking to DBpedia from Your FOAF Profile

As Wikipedia contains articles about many general-purpose concepts, DBpedia can also be seen as a huge ontology that assigns URIs to plenty of concepts and backs these URIs with with dereferenceable RDF descriptions.

If you have a FOAF profile and you need terms for describing your interests or your location, you might consider using DBpedia URIs. This will allow RDF browsers like Disco, Tabulator, or the OpenLink Data Web Browser, to browse from your FOAF profile into DBpedia. The links also allow clients like the Semantic Web Client Library to answer SPARQL queries over both data sources.
